WINDOW-"SHADE MACHINE- SPECIFICATION forming part of Letters Eatent No. 758,999, dated May 3, 1904. Applicatio-i filed September 17, 1902. Serial No. 123,796. (No model.)

To all whom it Tnay concern:

Be it known that 1, Manama F. MILLER, a citizen of the United States, residing at Indianola, in the county of \Varren and State of Iowa, have invented a certain new and useful \Vindow-Shade Machine, of which the follow ing is a specification.

The objrcts 0t my invention are to provide I A further object is to provide a windowshade machine in which there are cutting knives so arranged that one of these knives can be adjusted so that the material may be cut at any predetermined width when my machine is operated.

A further object is to provide a measuring device for determining the width of the ma terial in which one of the cutting-knives are adjustable and also to provide a measuring device by which the length of the shade material can be determined as the machine is operated.

A further and very material object of my invention is to provide means for attaching the window-shade strip to the lower end of the shade material and to attach this strip firmly at the lower end of the window-shade material without stitching it, as is customary at the present time.

A further object is to provide a machine of the class mentioned which can be operated wholly from the front of the machine after the roll of material has been adjusted at the rear thereof.

A further object is to provide means for rolling the shade fabric upon the roller to which the front end of it is attached and to accomplish this result at the same time and by operating the same parts of the device as when cutting and measuringthe shade r fabric. l

A further object is to provide a plunger in my machine which can be operatedto. force that portion of the fabric which is beneath its lower edge into the particular form of 'win- (low-shade strip which is used byme.

Forv the purpose of making the description more clear it will be well to state that the front side of the machine is the front as shown in Figure 1 of the drawings and the side at which the operator does his work.

My invention consists in certain details in the construction, arrangement, and combination of the various parts of'thc devicev whereby the objects contemplated are attained, as 1 hereinafter more fully set forth, pointed out a in my claims, and illustrated in the accompanying drawings, in wlnch- Fig. l is a perspective view of the complete window-shade machine.

Fig: 3 is a Fig. 4 1s an end plan view of my device. elevation of the device, this view showing the Fig. 4. Fig. 6 shows in perspective the particuiar form of window-shade strip'which is used when using my machine and shows the wheel device which is used in adjusting the cord at the lower portion of the slot in said, strip. Fig. 7 is a detail view of the lower' end of the wheel device shown in Fig. 6 witha portion of the handle broken away. Fig.

8 is'an end view of the particular formof strip to which the window fabric is attached and a piece of the fabric attached to said strip. Fig. 9 is a cross-sectional view of the upper portion of my machine, cut through the line 3 3 of Fig. 3 looking toward that end of 1 0 Fig. 2 isa front ele- .3 vation of the device with an attachment on top of the plunger to which machine-power can be applied to operate the plunger when dew This attachment is a A y A v the device to which the wheel for operating a portion of the mechanism is attached. Fig. 10 is adetail view of the cutting mechanism attached near one end of 1 the main rollers 5 which cuts one end of the shade fabric and shows the way in which the main rollers are supported in the frame. Fig. 11 is a crosssectional view of the main rollers, showing the same portion of these rollers as is illus l trated in Fig. 10, also showing the cuttingknives on said rollers. Fig. 12 isa front ele vation of the main rollers and the means of attaching them to the frame with the end away from the wheel for operating the device broken away. This figure is designed to show the way in which the shade-roller is mounted above the frame after the shade fabric has been attached to it so that the shade fabric can be rolled upon the roller. Fig. 13 2 is a cross-sectional view of my plunger and the sliding platform which supports the windew-strip beneath the plunger. This view shows the position of the fabric before the plunger has been moved downwardly. This 2 5 View also shows the way in which the plunger is mounted on the frame of my device, and Fig. 14 shows the same mechanism as Fig. 13 with the plunger at its lower limit of movement and a portion of the fabric pushed into 3o the longitudinal slot in the window-shade strip. Fig. is a detail view of the plunger, showing an attachment with which a power machine may be connected for operating said plunger.

Referring to the accompanying drawings, I have used the reference-numeral 10 to indicate the platform to which my machine is attached. This platform is supported by the legs 11 on its under surface. Two of these 4 legs 11 are attachedat one end of the platform 10 and the opposite sides thereof, and the other two of these legs are attached at the other end of my platform and the opposite sides thereof. Attached to the legs 11 at one end of the frame is the connecting-strip 13,

extending longitudinally of the machine. Beneath the platform 10 and attached to the connecting-strips 12 and 13 is the longitudinal brace 14. The legs 11 at one end of the frame 5 are connected at their top portion by means of the brace 15, which is also attached to the lower surface of the platform 10. I have provided a corresponding brace 16 at the opposite end of the platform, connecting the legs 11 attached thereto. Firmly mounted to the top of the platform 10 and at the rear side thereof is the rod-support 17. This rod-support17 is near that end of the frame to which the brace 15 is attached. Adjustably mounted on the platform 10 and parallel with the rodsupport 17 is the rod'support 18, which is designed to support the opposite end of the rod from that which is supported by the support 17 This support 18 is made adjustable, so 5 that any desirable length rod can be placed on the supports 17 and 18. Detachabl y mounted in the rod-supports 17 and 18 is the rod 19, having the disks 2!) thereon. These disks 20 are detachably connected with the rod 19, so that they can be removed from the rod and allow the operator to slip a roll of shade fabric on the rod 19, and when the fabric has been placed upon the rod 19 the disks are readjusted on. this rod and keep the fabric in position on it when being uurolled. Attached to the top of the platform 10 and immediately in front of the rod-supports 17 and 18 is the measuring-strip 21, and mounted on said measuringstrip and near the rod-support 17 is the fabricguide 22. Adjustably mounted on the measuring-strip 21 is the knife-bearing guide 23, said knife-bearing guide having the knife 24 mounted at one end thereof and extending upwardly and rearwardly from its point of at tachment, so that the cutting edge thereof is nearest the rod 19. It will be seen that by adjusting the knife-bearing guide 24 in position so that the cutting edge of the knife engages the fabric as it is drawn forwardly above the platform the knife 2 will cut the material as it engages said knife.

Mounted at one end of the platform 10 and in front of the measuring-strip 21 is the ro ler-support 25. At the opposite end of the platform 10 from that to which the support 25 is attached is the roller-support 26. The roller-supports 25 and 26 are substantially parallel with each other and extend upwardly from and at right angles to the platform 10. Connecting the top portion of the supports 25 and 26 is the connecting-piece 27, having a semicircular groove extending longitudinally of it. Mounted between the roller-supports 25 and 26 are therollers' 28 and 29, said rollers being in engagement with each other and covered throughout their length by felt or other material of a similar character. Near one end of the rollers 28 and 29, with their cutting edges in engagement with each other, are the disk knives 30 and 31, said disk knife 30 encircling the roller 28 and the disk knife 31 encircling the roller 29. The disk knives 30 and 31 are so arranged that the cutting edges will be constantly in engagement with each other as the rollers are rotated. Vl'hen a piece of fabric is passed between the rollers and between the cutting edges of the disk knives 30 and 31, the fabric will be cut when the rollers 28 and 29, hearing the disk knives, are rotated. These knives are designed to cut one edge of the fabric while the knife 24 is cutting the opposite edge of the fabric. It will be seen that as the fabric is moved toward the front of the machine and over the platform 10 between the rollers 28 and 29 the material will be cut at any desirable width after having adjusted the knife-bearing guide 23 before the fabric is passed between the rollers 28 and 29.

On the outside of the roller-support 25 and projecting outwardly therefrom is the axle 32.

Mounted on said axle32 is the cog-wheel 33, having the cogs on the interior thereof. Attached to said wheel and outside thereof is the handle 34, by which said wheel can be rotated on its axle. Mounted on the exterior end of the roller-support 35, which supports the roller 28 at one end and projects outside of the roller-swgport25, is the cog-wheel 36, the cogs of said wheel being designed to engage the cogs on the interior of the cog-wheel 36 when it is rotated on its axles. The cogwheel 33 has a groove in its outer periphery for purposes hereinafter made clear. As the cog-wheel 33 is rotated in a direction toward the rear of the machine the roller 28 will be rotated in a direction toward the front end of the machine on account of the change of motion which is effected by means of the cogwheel 36 acting on the cogs of the wheel 33. Thus as the roller 28 is rotated in a direction toward the front side of the machine the roller 29 will be correspondingly rotated on account of the rough surface of the roller 28 engaging the rough surface of the roller 29, which rough surface is provided by means of felt or substance of a similar nature, and the shade fabric which is placed between these rollers 28 and 29 will be moved toward the frontof the machine when these rollers are operated as above designated. If for any reason it should be desirable to move the fabric toward the rear side of the machine, motion of the rollers can be reversed by turning the cogwheel in the opposite direction from that above indicated.

Mounted above the connecting-piece 27 and immediately above theiroller-support 25 is the prong-bearing axle 37, having the prongs 38 on its interior end and the grooved wheel 39 at its exterior end, the groove in said grooved wheel 39 being directly above the groove in the wheel Passed around the wheel 39 and the wheel 33 is the belt 40, said belt being placed in the grooves in said wheels, S(. that as the wheel 33 is rotated the wheel 39 will be correspondingly rotated and in the same direction, thus turning the prong-bearing axle in the same direction as the wheel 39. This prong-bearing axle forms one end of my device for supporting the roller after the fabric has been attached to it and for rolling the fabric upon said roller. Adjustably mounted upon the connecting-piece 27 is the adjustable support 41 ,"which has the thumbscrew 42 extending through a portion of it, so that the inner end of said thump-screw engages the forward side of the connecting piece 27. The said thumb-screw is designed when properly adjusted to hold the support 41 in position relative to. the connecting-piece 27.

Ad justably mount-ed in the top of the support 41 is the hollow. rod 43, said rod having the thumb-screw 445m engagement with it and passing through the top portion of the support 41 to hold the hollow rod 43 in position relative to the support 41. Thus the rod 43 can be adjusted relative to the connectingpiece 27 in two ways. This rod 43 is designed to support the opposite end of the roller to which the fabric is to be attached from the pronged axle 37 and hold said roller substantially parallel with the connecting-piece 27. This rod 43 is made hollow, so that the projection on the end of the roller can enter the opening in the central portion of the rod 43. The prongs 36 of the pronged axle 37 engage the mechanism at the opposite end of the roller from that which is held in position by the hollow rod 43. Thus as the roller is rotated by means of the prong-bearing axle and the mechanism by which it is driven the rod in the shade-roller at the opposite end of the shade-roller from that which is engaged by the pronged axle will rotate freely in the rod 43. In the front'of the roller-bearing supports 25'and 26 are two plunger-supports 45, said supports being attached at opposite ends of the platform 10, substantially at rightangles to said platform and extending upwardl y therefrom. To the tops of the plungersupports 45 and extending at right angles to and inwardly from said supports are the brackets 46, having the coiled springs 47 attached to their inner ends and extending downwardly therefrom to their point of attachment 48 atthe ends of the plunger 49. Said plunger is limited to a vertical movement by means of the grooves 50 on the interior of the supports 45. thick at its top portion and tapers to its mini mum in a metal blade 51 at its lower portion, said metal blade 51 extending longitudinally of the plunger and forming part of it.

Pivotally attached to the connecting-pieces- 12 and 13 are the bars 52 and 53, said bars extending forwardly from their points of attachment, so that they extend a slight distance in front of the forward legs 11. (Jonnecting the front ends of the bars 52 and 53 is the bar 54, so that when the pressure is applied on top of the .bar 54 the forward end bars 52 and 53 will be moved downwardly. Attached to one end of the plunger 49 and to the bar 52 in front of its pivotal point is the rod 55. Attached to the opposite end of the plunger 49 from that to which the rod 55 is attached is the rod 56, which is attached at its lower end to the bar 53, said point of attachment of the rod 56 to the bar 53 being in front of the pivotal point of the bar 53. The rods 55 and 56 are constantly drawn upwardly by means of springs 57, which are attached to them and to the platform 10. These rods 55 and 56 are also drawn upwardly bymeans of their being attached to the plunger 49, which is drawn upwardly by the springs 47. Mounted on the platform ll) and near the front edge thereof is the sliding platform 58, said platform being capable of horizontal movement relative to the platform, and the The plunger 49 is quite forward movement of said platform is limited,

however, by the steps 59, which are attached 5 The sliding I plattorinis held against longitudinal inoveinto the groovr'ho I to the front of the platform 10.

ment of the platform 10 by means of the retaining-strips 60, which are at each end of the sliding platform and attached to the platform 10.

Detachably mounted at the front edge of the sliding platform and in its top portion is the roller 61, said roller extending through substantially the entire length of the sliding platform. Mounted on top of the sliding platform and near the rear edge thereof is the grooved retaining-strip 62. Said retainingstrip extends parallel to the roller61 and substantially the entire length of the sliding platform and is so arranged that the grooved portion is in its upper portion. Near the central portion of the sliding platform is a bandle 63, designed to be grasped by the operator in sliding the platform 58 forwardly or rearwardly relative to the platform 10. The

groove in the upper portion of the grooved strip 62- is designed to be immediately beneath the blade 51 of the plunger 49 when the sliding platform is at its inner limit of move ment. The entire slidingplatform aside from the roller is preferably made of metal, so that when the plunger is drawn downwardly the metal will stand the pressure of the plunger. The groove in the grooved strip 62 is designed to receive the window-shade strip which 1 use for the lower end of the fabric. This window-shade strip is constructed as follows: The body portion is made of wood and is oblong in cross-section. This strip is made of any desirable length, and in its top edge and extending longitudinally of it is agroove. the sides of which are substantially parallel with each other, said groove extending downwardly to the central portion of the strip. Beneath this groove there is an enlarged circular portion designed to receive a cord after the fabric has been passed into the groove, as will be more fully described hereinafter. The particular form of window-shade strip which is used is shown best by the end view shown in Fig. 8 of the drawings, and th way the fabric is put in is shown in Fig. 6 of the drawings, so that from these views it will be seen this strip has the wooden portion 64. which is oblong in crosssection, and it has the groove 65 with parallel sides and also has the longitudinal circular opening 66 beneath the sides, and the said longitudinal circular opening is designed to receive the rope 67 therein. It will be seen that as the fabric is drawn over my particular form of window-shade strip 64, which is placed in the groove in the retaining-strip 62 on the sliding platform 58, and the sliding platform is at its rearward limit of movement, and the groove 65 in the window-shade strip is beneath the blade 51 of the plunger 49 when the plunger is moved downwardly to the position showp 1 v in 's, the fabric will be pushed dounu ue b 'n the wimlow-shade strip, nger is raised upwardlwthc fabric will remain in the. groove be. lhe practical operation, iowevcr, of this device is mor fully disclosed hereinafter. y

Moi nted to the pllinger-support 4:) sand on the interim thereof is the idler ()8. lassed around the, idler 68 and the roller 29 is tlui measuring-strap (3). This strap is ad uster. between the rollers 27 and .28, and on account of these rollersroniing in close contact with each other as they are rotated the measuringstrap will measure the length of the fabric which is in the machine and between the rollers 28 and 29.

as set forth lill0tOfm'0. The fabr": is then passed beneath the sliding platform 58 and underneath the roller 61. lhcn as it passes outside of this roller (51 the fabric is drawn rearwardly by the operator and passed over the sliding platform and beneath the plunger 49 until the l'al-ric reaches the roller whiclr is placed in the semic rcular groove at toe top of the connecting-plecc 27. lhe operator then tacks the fabric to the roller. W hen the fabric has been attached to thcroller, the up; orator places the roller between the prongci axle 37 and the adjustable hollow rod 4-5. lie then turns the crank 34, which causes the cog-wheel 33 to be rotated, the 213th vi to )e rotated, and the rollers 2H and 1 also to )e rotated, thus causing the illlH'lC to .ic rol :l upon the shmlc-rollor. As the rollers 28 am 29 are rotated the length of the fabric can be determined by watching the measuring-strap and when the. phi

in the window-shin holding the spool means of the thuml ed on the support in practical use, sliding platform is movement, the opera to he made.

in Fig. 14 of the draw- 15 is the spool 70, con- 7, which is designed to be 69, which passes between said rollers. When the operator has sufiiuicizt fabric on the shaderoller, he moves the sliding platform to its inner limit of movement and adjusts the window-shade strip in the slot at the top of the retaining-strip 62 in such away that the groovein said window-shade strip will come directly beneath the blade 51 of the plunger bar 47, which causes the blade 51 of the plunger 49 to be drawn downwardly against the fabric, so that the fabric will be forced into the groove 65 in the window-shade strip. He then allows the plunger to bedrawn by the springs 47, 55, and 56 to its upper limit of movement. He then draws the sliding platform to its forward limit of movement and runs a knife throughout the entire length of the groove 65 in tl1e.retaining-strip, so that he severs the fabric which is now attached to the roller and in the groove 65 from that fabric which is attached to the supply-roll. He then rotates the-\vindow-shade strip in a direction toward the front of the machine after 1 having removed it from the groove at the top of the retaining-strip 62. Il'hen he has given it a complete revolution, he again places the window-shade strip in the groove at the top of the retaining-strip 62 and after having moved the sliding platform 58 to its inner limit of movement draws down the plunger 49 again and causes the blade 51 thereon to force the fabric into the groove 65 in the window-shade strip. He then moves the sliding platform to its forward limit of movement. He then draws the cord 67 upwardly and places it above the groove 65 in the window-shade strip and forces the cord 67 into the circular opening 66 at the bottom of the groove 65 by means of the wheel-bearing device 79.. Said wheel-bearing device has the wheel 73 thereon, said wheel having a groove in its outer periphery and has sharp edges on its sides, so that the rope will enter this groove 74 when the wheel 73 is rotated over it. He then severs the end of the cord which is nearest the supply-spool and at the end of the window-shade strip. The window-shade strip is then removed from the groove at the top of the retaining-strip 62, and the shaderoller is removed from the machine, and the window-shade is in condition for use. As

soon as these are removed the machine is in readiness for use in making another windowshade. The way in which the material passes over the parts of the machine is best illustratcd in Fig. 5 of the drawings. The way in which the plunger forces the fabric into the groove (35 of the window-shade strip is best-shown in Fig. 8 of the drawings. This shows the exact position of the fabric relative to the window-shade strip. I have provided an attachment 72*, which is designed to be mounted at the top of the plunger 49, to which power can readily be applied, and thus e then places his foot upon the v beneath this second plunger the obviate the necessity of manually operating the plunger. This is simply a modified form of my device, however, and this attachmentis shown only in Fig. 2 of the drawings.

Fig. 15 shows a modified form of the ront portion of my end plunger, the blade of which has a semicircular groove in its lower portion so arranged that when the sliding platform is moved cord after ithas been placed above the window-shade strip can be inserted into the longitudinal groove by means of this plunger. This plunger is attached to the machine in the same way as the plunger referred to in the short description of Figs. 13 and 14.

It will be clearly seen that by the use of this devicethe necessity of using the grooved roller will be obviated. Thus by simply adjusting the sliding platform and moving it horizontally the'second plunger can be readily and easily used to insert the cord into the longitudinal groove of the wimlow-shade strip which is used by me dow-shade fabric with my device.

It is obvious that the machine can be used for making more than one shade at a time device, in which I show a secwhen attaching the winwhen the fabric is of sufficient width to guarantee doing this by simply placing two wmdow-shade rollers at the top of my device and having two strips for the lower end of my window-shade fabric.
